The Big Wheel 70cm Horizontal Polarized Omni Directional Antenna Ham Radio
The "Big Wheel" is a horizontal polarized omni directional antenna. Usually highly directional antennas are used on VHF and UHF, which have the capability to bundle the radiated energy in one direction and eliminate interferences from unwanted directions. But these effects are not always welcome. With directional antennas it is nearly impossible to monitor a frequency for signals from any direction. Usually the directional antenna stays in the direction where the most signals are expected from and some rare contact in an other direction is lost.
In such cases the Big Wheel is an ideal antenna which should be used together with a directional antenna. Big Wheel antennas by WiMo are made of stainless aluminum, all other hardware is made of stainless steel. The antenna gain is approx.3dBD, each Big Wheel has a N-jack (female). By vertical stacking of two Big Wheels you get a gain of approx. To connect two antennas to one coax feed a usual phasing harness can be used. Stacking of Big Wheel Antennas To achieve a higher gain, Big Wheel antennas can be stocked vertically.
With such a configuration either 2, 4 or 8 antennas are used. The antennas are connected with 2 (4,8) cables of exactly the same length to a 2-way (4-way, 8-way) power splitter. This solution is also suitable for higher power levels (> 100W). Weight 0,7 0,3 Kg.
